Cultural Resources Technical Report for PacifiCorp’s Weber Hydroelectric Project Relicensing, Weber, Morgan, and Davis Counties, Utah, FERC Project No. 1744 Report Date. September 8, 2016 Agency Name. Federal Energy Regulatory Commission (FERC); Uinta-Wasatch-Cache National Forest (U-W-CNF) Permit Number. Public Lands Policy Coordination Office (PLPCO) Permit Nos. 20 and 180 Land Ownership Status. U-W-CNF; Private Project Description. PacifiCorp plans to file a new application for relicense of a major project, the Weber Hydroelectric Project, FERC Project No. 1744, on the Weber River in Weber, Morgan, and Davis Counties in Utah. The current license will expire on May 31, 2020. In July 2015, PacifiCorp requested SWCA Environmental Consultants (SWCA) to conduct a formal cultural resource inventory of the Project Area to support the relicensing process. Project Number. SWCA Project No. 35579; Utah State Antiquities Project No. U-15-ST-0777fp Project Location. The Project Area is located in Sections 28–30, Township 5 North, Range 1 East, Weber, Morgan, and Davis Counties, Utah, Salt Lake Meridian, on the Ogden (2001) U.S. Geological Survey, Utah, 7.5-minute quadrangle. Number of Acres Surveyed. SWCA inventoried a total of 59.97 acres (24.27 hectares [ha]). Of these, 17.05 acres (6.88 ha) were intensively surveyed, 34.45 acres (13.94 ha) were surveyed at a reconnaissance level, and 8.46 acres (3.40 ha) were not surveyed because they are existing paved roads. Of the 59.97 acres (24.27 ha), 29.93 acres (12.11 ha) are on privately owned lands and 30.04 acres (12.16 ha) are on lands administered by the U.S. Forest Service. National Register of Historic Places– (NRHP–) Eligible Sites. Three sites: 42DV184/42WB344/42MO59, 42MO75/42WB523, and 42WB328. NRHP-Ineligible Sites. None. Recommendations. SWCA documented two sites during the inventory of the Project Area: 42DV184/42WB344/42MO59 (a segment of the Union Pacific Railroad) and 42MO75/42WB523 (a previously unrecorded segment of historic U.S. Highway 30 South (U.S. 30S). The new segment of the Union Pacific Railroad is considered a contributing segment of the site and is recommended eligible for the NRHP under Criterion A. U.S. 30S is a historic highway through Weber Canyon that is now Interstate 84. SWCA recommends U.S. 30S eligible for the NRHP under Criterion A. The Devil’s Gate Weber Hydroelectric Power Plant Historic District (42WB328) has been previously documented, and no updated documentation is needed; the district was added to the NRHP in 1989. With the exception of potential fish passage facilities, there are no proposed changes to the existing Project facilities or infrastructure that could adversely affect these sites. Any impacts from fish passage construction or continued operation of the Project would occur within the FERC Project Boundary. PacifiCorp prepared and implemented a cultural resource management plan as part of their 1990 FERC license to address potential adverse impacts from the Project. PacifiCorp will follow the standards and procedures outlined in the plan (and modify the document as necessary) in coordination with the State i DRAFT Cultural Resources Technical Report PacifiCorp’s Weber Hydroelectric Project Relicensing FERC Project No. 1744 Historic Preservation Office for proposed fish passage construction and continued operation and maintenance, as well as any new proposed construction. No significant impacts to cultural resources are expected from this re-licensing effort. Therefore, SWCA recommends no historic properties affected for this project. ii DRAFT Cultural Resources Technical Report PacifiCorp’s Weber Hydroelectric Project Relicensing FERC Project No. 1744 CONTENTS Abstract ......................................................................................................................................................... i Introduction ................................................................................................................................................. 1 Project Area ................................................................................................................................................. 1 Environment ................................................................................................................................................ 5 Cultural Context ......................................................................................................................................... 5 Early Exploration and Settlement (A.D. 1776–1870) ............................................................................... 5 Railroads ................................................................................................................................................... 6 Highways .................................................................................................................................................. 6 Previous Research ....................................................................................................................................... 7 Methods ........................................................................................................................................................ 9 Inventory Results and Evaluations .......................................................................................................... 10 42DV184/42WB344/42MO59, Union Pacific Railroad ......................................................................... 11 NRHP Recommendation ..................................................................................................................... 12 42MO75/42WB523, Historic U.S. 30S................................................................................................... 13 NRHP Recommendation ..................................................................................................................... 15 Management Summary ............................................................................................................................ 15 References Cited ........................................................................................................................................ 17 APPENDICES Appendix A.

The current license will expire on May 31, 2020. The Project has a generation capacity of 3.85 megawatts (MW) and is located partially on federal lands managed by the Uinta-Wasatch-Cache National Forest (U-W-CNF) and partially on private lands owned by the Union Pacific Railroad Company. PacifiCorp filed a Notice of Intent to File Application for New License (NOI) and a Pre-Application Document (PAD) to initiate the FERC’s Alternative Licensing Process (ALP) for the Project on May 29, 2015. During preparation of the PAD (PacifiCorp 2015), PacifiCorp conducted a desktop-level assessment to evaluate existing information on potential cultural resources in the Project Area and to assess potential Project impacts on these resources. In summary, the desktop assessment identified two cultural resource sites located in the Project Area (the Union Pacific Railroad and the Devil’s Gate Weber Hydroelectric Power Plant Historic District [the Weber Plant’s historic
